SMSL’s Flagship DAC

The VMV D2 is SMSL’s flagship DAC. Featuring an AKM AK4499EQ DAC chip, 16-core processor, and independent digital/analog power supplies, it decodes audiophile-grade files with top-of-the-line performance.

Flagship DAC Chip AKM AK4499EQ

The AKM AK4499EQ is AKM’s latest Velvet Sound Verita flagship DAC chip. Produced using the Premium Audio LSI process, this chip has incredible distortion and noise performance.

Qualcomm Bluetooth 5.0

The Qualcomm Bluetooth chip lets you use a wireless source, such as an iPhone or iPad. It supports UAT, LDAC, aptX-HD, AAC, SBC, and other encoding formats up to 24bit/192kHz.

Excellent performance

With distortion as low as 0.000068% (-123dB) and dynamic range as high as 131dB, the SMSL VMV D2 outputs essentially nothing but pure music.

16-core processor

USB audio is processed by an XMOS second-gen 16-core XU216 processor that supports native DSD512 and a 32-bit/768kHz sampling rate.

Low noise, low interference circuitry

Two British NORATEL transformers independently supply power to the digital and analog processes. This eliminates interference and reduces the output noise floor as low as 1.8uVrms.

Take a load off

The SMSL VMV D2’s fully functional remote lets you sit back, relax, and have full control over the DAC’s functionality. Buttons for menu, input selection, Bluetooth mode, and more let you operate the DAC from the comfort of your couch.

Six inputs

With six inputs, including USB, optical, coax, I2S, Bluetooth, and AES/EBU, the SMSL VMV D2 is compatible with all of your sources. Plug in a laptop, CD player, TV, iPad, and more. Use the remote or multi-function wheel to quickly switch between them.
